Answer:
$115.67
Step-by-step explanation:
given that the markdown rate is 53%, that means that the markdown is 53% of the original price, or,
markdown = 53% of $229.99 = 0.53 x 229.99 = $121.89
sale price before tax = Original Price - Markdown
= 229.99 - 121.89
= $108.10
sales tax = 7% of sale price before tax
= 0.07 x 108.10
= $7.57
Final price = price before tax + tax
= 108.1 + 7.57
= $115.67
Answer:
The answer is C
Step-by-step explanation:
I got my answer from quizlet
Answer:
son age: X
man_age= 5X
in 3 years: we have: (man_age+3)(X+3)=380
we can replace the man age by 5X and we get :
(5X+3)(X+3)=380
it is a quadratic equation with 2 solutions. One negative and 7
The solution is thus 7, since age can not be negative.
The son is thus 7 and the dad 5 times more 35

Answer:
0.97547
Step-by-step explanation:
Given That:
Mean (m) = 102
Standard deviation (σ) = 12
Sample size (n) = 63
Probability that sample mean would differ from Population mean by less than 3.4 watts
P(m - s < X < m + s)
P(102 - 3.4 < Z < 102 + 3.4)
Using the Z formula :
Zscore = (x - m) / (σ/√n)
x = 102 - 3.4 = 98.6 ; x = 102 + 3.4 = 105.4
Z = (98.6 - 102) / (12/√63) = −2.248888
P(Z < - 2.2488) = 0.012263 (Z probability calculator)
Z = (105.4 - 102) / (12/√63) = 2.2488886
P(Z < 2.2488) = 0.98774 (Z probability calculator)
0.98774 - 0.012263 = 0.97547
Angle between 16 and 18 = 90 + 55 = 145°
